LUBRICATSLNG SYSTEM.

Application filed March 22, 1926. Serial No. 96,369.

This invention relates to improvements in lubricating sys/tems'and refers more particularly to lubricating systems for locomotive driving boxes and side rod brasses.

Broadly speaking-this invention provide a lubricating' system wherein positive means are employed for continuously forcing a lubricant in small quantities into the vdriving boxes and side-rod brasse's as long as the locomotive on which the system is arranged travels in either direction.

A preferred embodiment of the invention is hereinafter more fully described with` the aid of the accompanying drawings, in which:

Figure 1 illustrates a plan view ofthe invention.

Figure 2 is a section on the line 2-2 of Figure 1.

Figure 3 is a general )lan view showing the-application of one lu ricator for allthe driving boxes and side rod brasses,

Referring now to the drawings, 1 designates ordinary locomotive frames having the line 6--6 of the usual axle boxes 2 mounted therein andv driving axles 3 journalled in the boxes.l Between the framesl and usually supported thereby is a platform 4 on which a lubricator 5 is secured. On one of the axles 3 a cam 6 is secured the periphery ofv which contacts a roller 7 revolvably mounted on the outer end 0f the rod 8 which is adapted t i reciprocate in bearings 9 of the lubricator. The spring 10 around the rod 8 holds the Vroller on the latter in engagement with the cam. A dog 11 pivotally mounted on the rod 8 engages theteeth of the ratchet wheel 12 which is xed on the shaft 13. On the latter is a sliding gear 14 which normally meshes with the gear 15. This gear 15 is provided with an internal thread which cooperates with the threaded portion 16 of the plunger rod. This rod extends through the rear wall of aims to 7 is a section on thel line 7-7' of.

the container 18 and terminates in a plunger 19.' 2O indicates discharge ,openings through the front of the container, and 21 is a filler connection usually closed as by a cap 21a. The back end 22 of the plunger is preferably smooth and. is supported by a bearing 23 integral with the lubricator casing 24. The plunger rod terminates in a nut 25 having'a collar 26 integral therewith. -A shifter 27 is supported by the oas-ing 24 and by a bearing 28 integral therewith, an-d is adapted to move longitudinally so that when the plunger has advanced to a predetermined position in the container the collar moves the shifter- 27 inwards therebyrotating the cut-out member 29 about its Afulerum point 30 and moving the 'sliding gear 14 out of engagement with the gear 15. occurs the continued rotation-of the shaft 13 will notI move the plunger. When the (container is to be reloaded the gear 15 must dicates pac ing which is sometimes em-v ployed to insure `tight joints around the axles. In the ways 34 split annular reF ceivers 35 are 'slidingly mounted so that the latter may remain stationary while the split collars 31 revolve with their axles 3. Integral withone of the sections of the reservoirs are projecting members 36 which pass through apertures 37 in the locking plates 38, which latter extend transversely between, and are supported by, the fram-es. It will After that be noted that whereas this arrangement prevents the l'reservoirs from revolving lateral and vertical movement of the projections 36 within the apertures 37 is permitted.

Through the reservoirs are holes 39 having flexible tubes 40 attached theretojf the opposite ends of which are connected to the discharge openings 2O of the container.

The axles 3 are hollow and have tightly plugged ends 41. 42 indicates passages from the interior of the reservoirs 35 into the bores of the axles. Onto the journals 43 raf brasses 48.

' -may be substituted therefor.

tw! man ,'lhe side rod brasses are ilnlicatcd at 4S,

The operation ot the system is as tollon's: is the axles 3 rotate the cam (i reciprocates the rod 8 thereby gradually advancing the plunger lt) and 'forcing grease through the tubes 40 into the reservoirs U5. From the latter the lubricant pas-sm through the bollov axles and, 'either through the openings 44 to the journals 43, or else through the passages 45 to the inside ot the side rod Obviously the cam 6 may, it desired, be made integral with one of thev split collars 3l as shown at 3l in Figure 9.

Moreover though one torm ot luln-icator has been shown and described it is understood that any other lubricator so constructed that the lubricant will be continuously forced theret'rom as they locomotive travels rlhe lubricator must however be provided with automatic means for cutting out the forward travel ot' the plunger' when the lattcr has reached a predetermined point.

The feed ot the lubricator may it preferred be obtained from any other moving p art ot the locomotive. the movement hoivever shouldv be such that pressure will be exerted on the lubricant irrespective ot the direction dt travel of the locomotive.

While in the foregoing the preferred cmloodiment of the invention has been described and shown, it is understood that the construction herein described Yis susceptible to such modifications as :tall Within the scope of the appended claims.
